Bill payment system and method

ABSTRACT

A system and method to use quick response (QR) codes encoded with a bill from a merchant, such as, for example, provided by a restaurant. A code scanner ( 106 ) can scan a QR code that encodes a merchant identification code that identifies a merchant. A user can select a payment instrument on the code scanner for paying the bill. The code scanner can transmit to an application server ( 102 ) data pertaining to the payment instrument. The code scanner can receive from the application server status data indicating whether the bill was successfully or unsuccessfully paid.

PRIORITY CLAIMS

This application claims the benefit of GB Application No. 1119375.2, filed Nov. 10, 2011, and claims the benefit of U.S. Provisional Application No. 61/587,416, filed Jan. 17, 2012. GB Application 1119375.2 and U.S. Provisional Application No. 61/587,416 are incorporated herein by reference for all purposes.

BACKGROUND

Bill payment at establishments such as restaurants, refuelling stations and retailers can be tedious and time-consuming. For example, at a restaurant, when a diner is presented with a bill at the conclusion of a meal, the diner can tender cash or a payment instrument (such as a credit or debit card) to a waiter in order to pay the bill. The waiter is then required to provide change if payment is by cash, or to use a point-of-sale (“POS”) terminal if a payment instrument is used.

A further illustration of the tediousness of bill payment occurs where a diner elects to add a discretionary gratuity (or “tip”) to the bill total as a reward for good service, or elects to deduct or alter an optional gratuity is already reflected in the bill total. Still further, the diner may wish to split the bill total, with or without a gratuity, equally with fellow-diners, or the diners may agree that each person pays for the items on the bill that each person has consumed.

The applicant has appreciated the desirability of a simpler process for paying bills than that described above.

II. Example Architecture

FIG. 1 depicts a schematic representation of a system 100 for payment of bills in accordance with example embodiments described herein. The system 100 includes an application server 102, a POS terminal 104, a code scanner 106 device configured to scan and decode Quick Response (QR) codes which are well known and widely used, and a merchant terminal 108. The code scanner 106 can take the form of a conventional smartphone handset provisioned with software for scanning QR codes, a web browser, and a wireless connection to the internet. The code scanner 106 can be referred to as a “mobile wireless communication device,” a “mobile smartphone handset” or, more simply, a “mobile smartphone” or “smartphone.” As an example, the mobile wireless communication device can be a personal digital assistant or a cellular telephone. As another example, the mobile wireless communication device can be an iPhone, such as the iPhone5, or an iPad sold by Apple Inc., Cupertino, Calif., United States. The code scanner 106 does not need to be a mobile device, but can be a device that remains attached to a stationary internet-enabled device.

The merchant terminal 108 can take the form of a conventional smartphone handset provisioned with a web browser and a wireless connection to the internet. The merchant terminal 108 can be referred to as a “merchant wireless communication device”, a “merchant smartphone handset” or, more simply, a “merchant smartphone”. As an example, the merchant wireless communication device can be a personal digital assistant or a cellular telephone. The merchant wireless communication device 108 does not need to be a mobile device, but can be a device that remains attached to a stationary internet-enabled device.

The application server 102, the POS terminal 104, the code scanner 106 and the merchant terminal 108 can communicate with each other using a communication network 116. The communication network 116 can comprise a wide-area network, such as the internet.

Communication between the application server 102, the code scanner 106 and the merchant terminal 108 can be facilitated by using a server-hosted program (not shown), a scanner application program (a ‘scanner app’) that is installed and executed on the code scanner 106, and a merchant application program (a “merchant app”) that is installed and executed on the merchant terminal 108. In another respect, communication between the application server 102 and code scanner 106 can occur using network interface 152 (shown in FIG. 4) and network interface 176 (shown in FIG. 6).

A user can download a copy of the scanner app from a download repository (for example, data storage device 178 in FIG. 4) and install the scanner app on the code scanner 106. On, during, or after installation, the scanner app creates a user profile 110 on the code scanner 106 and prompts the user to manually provide personal attributes such as, the user's first name, the user's last name, an e-mail address, a physical address and particulars of one or more payment instruments such as credit cards, debit cards, e-wallets and the like. In accordance with at least some example embodiments, the user profile 110 (for example, the data in the user profile 110) is stored locally on the code scanner 106 and is not passed to the application server 102.

A merchant can download a copy of the merchant app from a download repository (for example, data storage device 178 in FIG. 4) and install the merchant app on the merchant terminal 108. The application server 102 hosts a merchant portal website 120 that enables merchants to register and create individual merchant profiles that are maintained by the application server 102 in a merchant database 112. The merchant portal website 120 can be referred to as a “portal website.” Merchant registration and creation of a merchant profile in the merchant database 112 can be performed online by the merchant portal website 120. A merchant can use a merchant computing device 130 including a display for displaying websites to display merchant portal websites and an input device for selecting or entering data onto the merchant portal websites.

FIG. 2 shows an example webpage 200 of the merchant portal website 120. The webpage 200 can display a registration form 201 that a merchant can complete in order to register with the merchant portal website 120. The webpage 200 can be a homepage of the merchant portal website 120. As an example, the registration form 201 can include the following fields: a merchant's business name 202, a merchant's business address 204, and a description of the merchant's business 206. As an example, the business description can be a restaurant, a motor vehicle repair shop, a retail store, or some other business description. Other examples of fields on the registration form 201 are possible. Entering data into the registration form 201 can occur, for example, by typing data or selecting data from a list of predetermined data.

A merchant can, in this manner, configure the merchant for QR-based bill payment. The application server 102 can assign a unique merchant identification code to each merchant business configured in this manner and the merchant identification code is stored in the merchant's profile in the merchant database 112. Additionally or alternatively, each merchant identification code can be provided to and stored with a QR source that serves QR codes to the POS terminal 104. For the sake of being brief, a merchant identification code can be referred to as an “identification code.”

In this description the terms ‘user’ and ‘customer’ are used interchangeably depending on the context. For example a user of the scanner app on the code scanner 106 can also be a customer of the merchant.

FIG. 3 illustrates an example QR code 999. QR code 999 can be encoded as a payment QR code.

III. Example Operation A

The system 100 can be used to register and pay a bill at a merchant business by use of the code scanner 106. The following example describes an application of the system 100 by a user (a diner) at a restaurant who wishes to pay a restaurant bill after completion of a meal. In addition to this particular example, the system 100 is also applicable to payment of other types of bills such as, for example, utility bills, traffic fines, online shopping bills and the like. The merchant (restaurant proprietor or manager) will have already downloaded the merchant app 196 from the application server 102, installed the merchant app on the merchant terminal 108, registered on the portal website 120 and created a merchant profile 142 in the merchant database 112. The merchant profile 142 includes a merchant identification code 140 assigned by the application server 102.

FIG. 7 is a flow chart depicting a set of functions 750 that can be carried out in accordance with an example embodiment. The set of functions 750 can be performed to pay the restaurant bill. The set of functions 750 are shown within blocks 700 through 738. A description of those blocks now follows.

Upon completion of the meal the diner can request a bill for payment from a waiter. The waiter can draw up a bill that contains, for example, a name and address of the restaurant, a waiter identification, a table number, a description and a corresponding cost of each item consumed during the meal, any tax such as sales tax or value-added tax included in the bill, and a total amount due. At block 700 the POS terminal 104 can provide a payment QR code that encodes the merchant identification code 140 in the merchant profile 142, a bill identification code or number, and all the details contained in the bill. The payment QR code may be generated by the POS terminal 104 or may be served to the POS terminal by an external source of QR codes (not shown). At block 702 the waiter or merchant can use the merchant app 178 and the scanner 171 on the merchant terminal 108 to scan the payment QR code provided by the POS terminal 104. At block 704, the merchant app 178 decodes the scanned payment QR code to recover the encoded data that it contains, in particular the bill identification number and the bill details. At block 706, the merchant app 178 appends the bill identification number and the bill details to the bills database 180 on the merchant terminal 108 and marks the status of the bill as pending (or unpaid).

The bill and the payment QR code can be provided, individually or in combination, to the diner. For example, the POS terminal 104 may print a hardcopy of the bill that contains the payment QR code, or may print the QR code separately to a hardcopy of the bill. At block 708, the user can use the scanner app 164 and the scanner 156 to scan the payment QR code on the hardcopy of the bill. At block 710, the scanner app 164 decodes the scanned payment QR code to recover the encoded data that it contains namely, the merchant identification code, the bill identification number and the bill details. At block 712, the scanner app 164 displays a page 800 on the user interface 154 with all the bill details, as illustrated in FIG. 8. At block 714 of FIG. 7 the user can review the bill details displayed on page 800 and amend the displayed data, if necessary. After reviewing and amending the data on page 800, the user can select, at block 716, a payment instrument to pay the bill. At block 718 the user can accept the bill for payment. The scanner app then transmits to the application server 102, at block 720, the merchant identification code, the bill identification number, the amount due and the details of a payment instrument to be used for payment (for example, a credit or debit card number, a cardholders name, a card expiry date, a CVC, or a PIN, as stored in the user profile 110). Once the details of the selected payment instrument have been received at the application server 102, the particulars of the financial transaction (for example, the bill amount, and merchant and payment details) are sent to a payment processor (not shown) for processing (at block 722).

At block 724, the application server 102 can determine whether the payment was successful. The payment processor transmits a payment status indicator, for example, either successful or unsuccessful. If the payment status is successful, the application server 102 notifies the scanner app 164, at block 726, that payment has been successful and the displayed page refreshes to indicate that the diner's bill has been paid (block 728). If, on the other hand, the payment status is unsuccessful, the application server 102 notifies the scanner app 164, at block 730, that payment has been unsuccessful and the page displayed by the scanner app 164 refreshes to request the user to select a different payment instrument and re-attempt payment (block 732).

At block 734, if the payment status indicator is successful, the application server 102 can transmit the bill identification number and the amount paid by the user to the merchant terminal 108 for processing. The merchant terminal 108 provides the received data to the merchant app 178, which uses the bill identification code to perform a lookup in the bill database 180 and retrieve the corresponding bill details (block 736). At block 738, the merchant app updates the bill details to include the amount paid by the user on that bill and to update the status of the bill as paid.

As illustrated in FIG. 8, the bill details displayed on page 800 of the user interface 154 of the code scanner 102 consist of the name and address 802 of the restaurant, the merchant identification code 804, a waiter identity or code 806, a table number 808, and a description and cost 810 of each item consumed during the meal, and tax due 812. The bill details can also include a service charge 814 that is automatically added to the amount due. Page 800 also includes icons 816, 818, 820 and 822 that provide the user with an option to add a service charge to the amount due on the bill if not already included in the bill total, or to alter the amount of a service charge if already included. Icons 816, 818 and 820 relate to predefined service charge amounts as a percentage of the bill total, for example, 10%, 12.5% and 15% respectively, while icon 822 relates to a free-form entry field for service charge amounts that are different to the predefined service charge amounts.

Page 800 also displays icons 824 and 826 that allow the user to select a payment instrument to use to pay the merchant's bill. Icon 824 can be used to select an e-wallet with which to pay, while icon 826 can be used to select a debit card or a credit card with which to pay the bill. If the user profile 110 in the code scanner 106 contains details of more than one payment instrument, the user can be prompted to select a preferred payment instrument from a drop-down list displayed in the scanner app 164.

IV. Example Operation B

FIG. 9 is a flow chart that depicts a set of functions 950 that can be carried out in accordance with an alternative embodiment. The set of functions 950 can be performed to pay the restaurant bill. The set of function 950 are shown within blocks 900 through 936. A description of those blocks now follows.

Upon completion of the meal the diner can request a bill for payment from a waiter. The waiter can draw up a bill that contains, for example, a name and address of the restaurant, a waiter identification, a table number, a description and a corresponding cost of each item consumed during the meal, any tax included in the bill, and a total amount due. At block 900 the POS terminal 104 can provide a payment QR code that encodes the merchant identification code 140 in the merchant profile 142 and a bill identification code or number. The payment QR code may be generated by the POS terminal 104 or may be served to the POS terminal by an external source of QR codes (not shown). At block 902, the POS terminal 104 transmits the bill details and the bill identification number to the merchant terminal 108 for further processing. The merchant app 178 appends the bill identification number and the bill details to the bills database 180 on the merchant terminal 108 and marks the status of the bill as pending (block 904).

The POS terminal 104 can provide a hardcopy of the bill that displays the bill details and the payment QR code. At block 906 the user can use the scanner app 164 and the scanner 156 to scan the payment QR code on the hardcopy of the bill. At block 908, the scanner app decodes the scanned payment QR code to recover the encoded data that it contains namely the merchant identification code and the bill identification number. At block 910, the scanner app 164 displays a page on the user interface 154 that contains the merchant identification code and a free-form entry field in which the user can enter the amount due on the bill.

At block 912 the user can review and amend the displayed amount, for example, by adding a service charge to the amount due on the bill, or by altering the amount of a service charge that is already included in the bill. The user can select, at block 914, a payment instrument to pay the bill. At block 916 the user can accept the bill for payment. The scanner app 164 then transmits to the application server 102, at block 918, the merchant identification code, the bill identification number, the amount due and the details of a payment instrument to be used for payment (for example, a credit or debit card number, a cardholder's name, a card expiry date, a CVC, or a PIN, as stored in the user profile 110). Once the details of the selected payment instrument have been received at the application server 102, the particulars of the financial transaction (for example, the amount due, and merchant and payment details) are sent to a payment processor (not shown) for processing (at block 920).

At block 922, the application server 102 can determine whether the payment was successful. The payment processor transmits a payment status indicator, for example, either successful or unsuccessful. If the payment status is successful, the application server 102 notifies the scanner app 164, at block 924, that payment has been successful and the displayed page refreshes to indicate that the diner's bill has been paid (block 926). If, on the other hand, the payment status is unsuccessful, the application server 102 notifies the scanner app 164, at block 928, that payment has been unsuccessful and page displayed by the scanner app 164 refreshes to request the user to select a different payment instrument and re-attempt payment (block 930).

At block 932, if the payment status indicator is successful, the application server 102 can transmit the bill identification number and the amount paid by the user to the merchant terminal 108 for processing. The merchant terminal 108 provides the received data to the merchant app 178, which uses the bill identification code to perform a lookup in the bill database 180 and retrieve the corresponding bill details (block 934). At block 936, the merchant app updates the bill details to include the amount paid by the user on that bill and updates the status of the bill as paid.

V. Example Operation C

FIG. 10 is a flow chart that depicts a set of functions 1050 that can be carried out in accordance with a further alternative embodiment. The set of functions 1050 can be performed to pay the restaurant bill. The set of functions 1050 are shown within blocks 1000 through 1036. A description of those blocks now follows.

Upon completion of the meal the diner can request a bill for payment from a waiter. The waiter can draw up a bill that contains, for example, a name and address of the restaurant, a waiter identification, a table number, a description and a corresponding cost of each item consumed during the meal, any tax included in the bill, and a total amount due. At block 1000 the merchant or waiter affixes a sticker bearing a payment QR code onto a hardcopy of the bill. The payment QR code is a static QR code and encodes the merchant identification code 140 in the merchant profile 142.

At block 1002, the user can use the scanner app 164 and the scanner 156 to scan the payment QR code on the hardcopy bill. At block 1004, the scanner app 164 decodes the scanned payment QR code to recover the encoded data that it contains namely, the merchant identification code. At block 1006, the scanner app 164 displays a page on the user interface 154 that contains the merchant identification code and a free-form entry field in which the user can enter the amount due on the bill, the waiter identification code and the table number.

At block 1008 the user can review and amend the displayed amount due, for example, by adding a service charge to the amount due on the bill, or by altering the amount of a service charge that is already included in the amount due. The user can select, at block 1010, a payment instrument to pay the bill. At block 1012 the user can accept the bill for payment. The scanner app 164 then transmits to the application server 102, at block 1014, the merchant identification code, the waiter identification and table number, the amount due and the details of the selected payment instrument to be used for payment. Once the details of the selected payment instrument have been received at the application server 102, the particulars of the financial transaction (for example, the amount due and the payment details) are sent to a payment processor (not shown) for processing (at block 1016). At block 1018 the application server 102 transmits the waiter identification and table number, as well as the amount due, to the merchant terminal 108 where the merchant app 178 appends the waiter identification/table number and amount due to the bills database 180 as a new bill and marks the status of the bill as pending (block 1020).

At block 1022, the application server 102 can determine whether the payment was successful. The payment processor returns a payment status indicator, for example, either successful or unsuccessful. If the payment status is successful, the application server 102 notifies the scanner app 164, at block 1024, that payment has been successful and the displayed page refreshes to indicate that the diner's bill has been paid (block 1026). If, on the other hand, the payment status is unsuccessful, the application server 102 notifies the scanner app 164, at block 1028, that payment has been unsuccessful and the page displayed by the scanner 164 refreshes to request the user to select a different payment instrument and re-attempt payment (block 1030).

At block 1032, if the payment status indicator is successful, the application server 102 can transmit the waiter identification/table number and the amount paid by the user to the merchant terminal 108 for processing. The merchant terminal 108 provides the received data to the merchant app 178, which uses the waiter identification/table number to perform a lookup in the bill database 180 and retrieve the corresponding bill details (block 1034). At block 1036 the merchant app updates the bill details to include the amount paid by the user on that bill and updates the status of the bill as paid.

VI. Example Operation D

FIG. 11 is a flow chart that depicts a set of functions 1150 that can be carried out in accordance with a further alternative embodiment. The set of functions 1150 can be performed to pay the restaurant bill. The set of functions 1150 are shown within blocks 1100 through 1138. A description of those blocks now follows.

In this embodiment the merchant portal website 120 enables a merchant to define a template specification (not shown) of the bill layout that is used by the merchant's business. In particular, the template defines the areas on the merchant's hardcopy bill where the different bill attributes are located, for example, the merchant identification code, bill identification number, amount due, waiter identification, table number and the like. The template specification is stored in the merchant's profile 142 in the merchant database 112.

Furthermore, in this embodiment, the scanner app 164 and the scanner 156 can perform optical character recognition from an image.

Upon completion of the meal the diner can request a bill for payment from a waiter. The waiter can draw up a bill that contains, for example, a name and address of the restaurant, a waiter identification, a table number, a description and a corresponding cost of each item consumed during the meal, any tax included in the bill, and a total amount due. At block 1100 the waiter or merchant affixes a sticker bearing a payment QR code onto a hardcopy of the bill. The payment QR code is a static QR code that encodes only the merchant identification code 140 in the merchant profile 142.

At block 1102, the user can use the scanner app 164 and the scanner 156 to scan the QR code and to take an image of the entire hardcopy bill. At block 1104, the scanner app 164 decodes the scanned payment QR code to recover the encoded data that it contains namely, the merchant identification code. At block 1106 the scanner app 164 transmits the merchant identification code to the application server 102 and requests the template specification of the merchant's hardcopy bill. At block 1108, the application server 102 uses the merchant identification code to perform a lookup in the merchant profile in the merchant database 112. At block 1110, the application server 102 transmits the template specification to the code scanner 106. The code scanner 106 provides the template specification to the scanner app 164 which then performs optical character recognition on the image of the hardcopy bill in accordance with the template specification (block 1112). The optical character recognition results in the recovery of the waiter identification, table number and the amount due from the image of the bill.

At block 1114 the scanner app 164 displays a page on the user interface 150 that contains the merchant identification code, the amount due on the bill, the waiter identification and the table number. At block 1116 the user can review and amend the displayed amount due, for example, by adding a service charge to the amount due on the bill, or by altering the amount of a service charge that is already included in the amount due. The user can select, at block 1118, a payment instrument to pay the bill. At block 1120 the user can accept the bill for payment. The scanner app 164 then transmits to the application server 102, at block 1122, the merchant identification code, the waiter identification and table number, the amount due and the details of the selected payment instrument to be used for payment. Once the details of the selected payment instrument have been received at the application server 102, the particulars of the financial transaction (for example, the amount due and the payment details) are sent to a payment processor (not shown) for processing (at block 1124). At block 1126 the application server 102 transmits the waiter identification and table number, as well as the amount due, to the merchant terminal 108 where the merchant app 178 appends the waiter identification/table number and amount due to the bills database 180 as a new bill and marks the status of the bill as pending (block 1128).

At block 1130, the application server 102 can determine whether the payment was successful. The payment processor returns a payment status indicator, for example, either successful or unsuccessful. If the payment status is successful, the application server 102 notifies the scanner app 164, at block 1132, that payment has been successful and the displayed page refreshes to indicate that the diner's bill has been paid (block 1134). If, on the other hand, the payment status is unsuccessful, the application server 102 notifies the scanner app 164, at block 1136, that payment has been unsuccessful and the page displayed by the scanner 164 refreshes to request the user to select a different payment instrument and re-attempt payment (block 1138).

At block 1140, if the payment status indicator is successful, the application server 102 can transmit the waiter identification/table number and the amount paid by the user to the merchant terminal 108 for processing. The merchant terminal 108 provides the received data to the merchant app 178, which uses the waiter identification/table number to perform a lookup in the bill database 180 and retrieve the corresponding bill details (block 1142). At block 1144 the merchant app updates the bill details to include the amount paid by the user on that bill and updates the status of the bill as paid.

Clearly, numerous variations and permutations are possible to the embodiments without departing from the scope of this disclosure: Some of these variations and permutations are described below.

1. In accordance with one or more of the disclosed embodiments, the restaurant bill and the payment QR code can be presented to the user directly on an electronic display, for example an electronic display on the POS terminal 104, instead of in hardcopy form. The user can then scan the payment QR code directly from the electronic display in order to pay the bill. The POS terminal 104 can transmit the bill identification code and the bill details directly to the merchant terminal 108 for further processing, without requiring the merchant to scan the payment QR code by means of the merchant app 178 and the scanner 171 on the merchant terminal.

2. In accordance with one or more of the disclosed embodiments, instead of the user profile 110 being stored only on the code seamier 106, the profile can be replicated and stored on the application server 102 as well. In this embodiment, the scanner app 164 on the code scanner synchronises changes to the user profile 110 with the copy of the profile on the application server 102 as the changes occur, or periodically, or explicitly under user command. The copy of the user profile on the application server 102 can then be imported to a different code scanner, for example when the user changes smartphones or in the event the user loses or damages her code scanner 106.

3. In accordance with one or more of the disclosed embodiments, in order to improve security of the system 100, transmission of data from the user profile 110 to the application server 102 by the scanner app 164 can be encrypted.

4. In accordance with one or more of the disclosed embodiments, instead of the application server 102 sending the particulars of the financial transaction (for example, the amount due and the payment details) to a payment processor (not shown) for processing, the application server 102 can process the payment itself.

5. In accordance with one or more of the disclosed embodiments, the scanner app 164 on the code scanner 106 and the merchant app 178 on the merchant terminal 108 can be the same application that has two modes of operation, namely user and merchant modes, respectively. The application that executes on the code scanner 106 can operate in user mode by default while a merchant that has registered on the merchant portal website 120 and created a merchant profile in the merchant database 112 can configure the application that executes on the merchant terminal 108 to operate in merchant mode.

6. In accordance with one or more of the disclosed embodiments, as illustrated in FIG. 12, the bill details displayed on the user interface 154 of the code scanner 102 can also include icons 1202, 1204, 1206 and 1208 that provide the user with an option to split payment of the bill with fellow diners. Icons 1204, 1204, 1206 and 1208 correspond to splitting the bill 2, 3, 4 or 5 ways, respectively. In order to split the bill, the user activates one of the icons 1202, 1204, 1206 and 1208 as desired and the display on the user interface refreshes to show the total amount due (inclusive of any service charge) and a subtotal due for each of the diners that are to share payment. For example, if the user activates icon 1206 to split the bill four ways, the displayed page will show four subtotals due. The page includes an icon that the user can activate to split the total amount due equally between the diners that will pay, in which case the scanner app updates the subtotals due to show equal amounts. In addition, the page can include controls (for example, slider icons) to adjust each of the subtotals due, subject to the constraint that the sum of the subtotals due is equivalent to the total amount due. In order to pay the bill, each diner that is to share payment is required to pay that diner's subtotal due.

The use of Quick Response technology (QR codes), as described in the example embodiments, can enable user interactions in connection with bill payment at a merchant establishment to be conducted more efficiently than is possible by means of known prior art methods. Once a user has established a user profile 110, the user need only scan, by means of the code scanner 106, a QR code displayed on a merchant bill website in order to effect payment of the bill. The user is spared the tedium of having to tender cash or a physical payment instrument such as a credit or debit card for payment. It is anticipated that the use of QR codes for bill payment in this manner will reduce the tedium of bill payment.

Data in the user profile 110 is stored locally in the code scanner 106. This means that sensitive user data such as particulars of payment instruments like credit or debit cards need not be handed over to other persons such as, for example, a waiter or a merchant, thus reducing the possibility of such particulars being misappropriated.
